The evolution of gamma-secretase modulators (GSMs) through the introduction of novel heterocycles with the goal of aligning activity for reducing the levels of Aβ42 and properties consistent with a drug-like molecule are described. The insertion of a methoxypyridine motif within the tetracyclic scaffold provided compounds with improved activity for arresting Aβ42 production as well as improved properties, including solubility. In vivo pharmacokinetic analysis demonstrated that several compounds within the novel series were capable of crossing the BBB and accessing the therapeutic target. Treatment with methoxypyridine-derived compound 64 reduced Aβ42 levels in the plasma of J20 mice, in addition to reducing Aβ42 levels in the plasma and brain of Tg2576 mice.

Paragraph 0889; 0893, (2020/11/30)
The present invention relates to novel compounds and methods for the manufacture of inhibitors of deubiquitylating enzymes (DUBs). In particular, the invention relates to the inhibition of ubiquitin C-terminal hydrolase 30 or ubiquitin specific peptidase 30 (USP30). The novel compounds have formula (I): (Formula (I)) or are pharmaceutically acceptable salts thereof, wherein: R1a, R1b, R1c, R1d, R1e and R1f each independently represent hydrogen, optionally substituted C1-C6 alkyl or optionally substituted C3-C4 cycloalkyl, or R1b and R1c together form an optionally substituted C3-C6 cycloalkyl ring, or R1d and R1e together form an optionally substituted C3-C6 cycloalkyl ring; R2 represents hydrogen or optionally substituted C1-C6 alkyl; A represents an optionally further substituted 5 to 10 membered monocyclic or bicyclic heteroaryl, heterocyclyl or aryl ring; L represents a covalent bond or linker; B represents an optionally substituted 3 to 10 membered monocyclic or bicyclic heterocyclyl, heteroaryl, cycloalkyl or aryl ring; and when -A-L-B is at position x attachment to A is via a carbon ring atom of A, and either: A cannot be triazolopyridazinyl, triazolopyridinyl, imidazotriazinyl, imidazopyrazinyl or pyrrolopyrimidinyl; or B cannot be substituted with phenoxyl; or B cannot be cyclopentyl when L is an oxygen atom.

An efficient synthesis of pyridopyrazine-1,6-dione γ-secretase modulators (GSMs) is described. Our route features the construction of a crystalline lactone intermediate via a selective palladium-catalyzed 4-methylimidazole N1-arylation using the Buchwald Xantphos Pd G4 precatalyst, which does not require a preactivation step. The weak inorganic base KHCO3 was employed to minimize saponification of a particularly sensitive lactone substrate. Additional key transformations include DABAL-Me3-mediated lactone aminolysis and a mild TBD/ethyl trifluoroacetate mediated lactam ring closure to afford a representative GSM in high yield.
